den or eXtreme. recoil. The friction plates 10 now being impelledoutwardly by spring 9 effectively resist any sudden recoil of the draftsprings by virtue of the fact Vthat they maintain the loose frictionelemeiits 12 in frictional cooperation with the friction plates 8 andthe friction surfaces 5a. Consequently, the gear returns to normal witha practically constant movement which is free from any jar or recoildiie to acceleration by the draft springs.

I am aware that various changes and modifications may be made in theconstruction of the devices without departing from the spirit of myinvention as indicated in the following claims.

What Iclaim is:

l. A draft gear including a movable member, a draft spring cooperatingtherewith and effective in the direction of movement thereof, atransverse spring effective transversely of the direction of movement ofthe said member, friction plates cooperating with vsaid springs andfriction elements having frictional engagement with said friction'platesand said member, and being retained in cooperation therewith by saidsprings.

2. A draft rigging comprising in combination, a longitudinally movablecasing, a draft spring cooperating therewith and effective in thedirection of movement of said casing, a transverse spring effective in adirection transversely of Said draft spring, friction plates cooperatingwith said transverse spring, and friction elements cooperating with saidfriction plates, said draft spring and said casing and operable by thelatter to cause compression of said draft spring and said transversespring upon compression movement of said casing.

' 3. In a draft rigging, the combination of oppositelydisposed movablecasings, a draft yoke and draft lugs cooperatingtherewith, oppositelydisposed draft springs ",c'ooperat` A ing with said casings andeffective in the di- `friction plates and said draft springs and vetrection of movement thereof, a transverse spring disposed intermediatesaid draft springs and effective in a direction transversely thereof,friction plates cooperating with said transverse spring, and frictionelements cooperating with said casings, said operable by the casings toproduce compression of said `draft springs and said transverse springupon a pulling or bufiing movement of either of said casings.

4. In a draft rigging in combination, oppositely disposed casings,friction elements cooperating therewith,y said casings being providedwith frictionl faces cooperating with said friction elements andoperable to move the latter inwardly upon compression movement of'either of said casings and draft springs and a transverse spring havingfrictional cooperation with said friction elements and operating tooppose inward movement of said friction elements.

5. A draft rigging comprising the combination of movable casings, draftsprinffs ef fective in the direction of movement of said casings,friction plates cooperating with said draft springs, a transversespring, friction plates cooperating with said transverse spring, andfriction elements cooperating with said easings and with said first andsaid last mentioned frictipn plates, said friction elements constitutinga medium through which said casings and said friction plates cooperatein mutual opposition to Aone another.

6. In a draft rigging, a draft spring, a movable casing provided withinwardly presented diverging friction faces, a friction plate providedwith inwardly converging friction faces and cooperatin with said casingthrough the medium o the spring, transversely operating friction platespiovided with inwardly presented diverging faces and cooperating witheach other through a transversely acting spring, and loose frictionelements having frictional cooperation with said casing and saidfriction plates. r

7. In a draft rigging, longitudinally movable .friction plates,transversely movable friction plates, draft springs cooperating with theformer, a transverse spring cooperating witli the last mentionedfriction plates, friction elements cooperating with said longitudinallymovable and said transversely movable friction plates, and a mov ablemember having friction faces adapted to cooperate with said frictionelements to move the same on said friction plates.

8. In a device of the class described, oppositely movable casings,oppositely disposed draft springs cooperating therewith, a transverselyoperating spring disposed intermediate said draft springs, atransversely movable friction plate cooperating with said transversespring, and loose friction elements cooperating with said frictionplate, each of said friction elements also cooperating with a casing anda draft spring.

9. In a draft gear, members oppositely movable by buliing and pullingstresses, loose friction elements cooperating therewith` said membersbeing formed with friction faces, friction plates, draft springscooperating with said elements and friction plates and operable to movetheclements on the said plates, and a transverse spring cooperating withsaid friction elements and adapted to move the same on the frictionplates.

l0. In a draft gear, in combination, a pair of opposed casings, a pairoffspring-separated laterally movable meinbeis having in-y clined outerends, springs seated within tlie casings,^ andwedging elementsinterposed llt mennen between the sprmgs vand the laterally nauw ablemembers.

11. ln a draft gear, in combination, a pailk of casings having theirside walls Haring: a laterally compressible abutment between thecasings, springs seated within the caa-A ings, a set of wedging elementsinterposed between each spring and the abutment.

121 ln a draft gear, incombination, a pair of easings, a laterallycompressible abutment between the casings, and comprising a pair ofcbambered members whose outer ends are wedge-shape and a spring urgingsuh'men1- bers apart, sprin s seated Within theoas ings, and a set ofriction elements located between each of the last-named springs and theabutment.

13. In a draft gear, inoombination,two

clined faces in lfn testimony whereof l hereunto am my presence of twowitnesses, 8i

si ature in the I thls 3d dayof June, 19.14.
